Product Introduction
When shaft vibration threatens uptime, the Bently Nevada 330173-07-11-10-02-00 3300 5mm Probe provides precise proximity measurement. This M8 x 1 thread probe, without armor, is built for industrial automation and predictive maintenance environments. The model number defines a 70 mm unthreaded length, 110 mm overall case length, and a 1.0 metre (3.3 feet) total length with miniature coaxial ClickLoc connector. Made in the U.S.A., this probe pairs with 3300 proximity transducer systems.
Technical Specifications Breakdown
The electrical and mechanical design of the Bently Nevada 330173-07-11-10-02-00 delivers stable readings under demanding conditions.
-
Power supply: Requires -17.5 Vdc to -26 Vdc at 12 mA maximum consumption. Operating above -23.5 Vdc may reduce linear range.
-
Sensitivity: Less than 2 mV change in output voltage per volt change in input voltage.
-
Probe DC resistance: 7.59 ± 0.50 Ω for the 1.0 metre length, measured from center conductor to outer conductor.
-
Probe case torque: 5.1 N·m recommended, 7.3 N·m maximum. Connector-to-connector torque maximum is 0.565 N·m.
-
Temperature range: -35°C to +177°C (-31°F to +351°F); exposing the probe below -34°C may damage the pressure seal.

Real-World Applications
In rotating machinery monitoring, the Bently Nevada 330173-07-11-10-02-00 measures shaft position and vibration through eddy-current proximity sensing. Typical installations include compressors, turbines, pumps, and electric motors where bearing clearance and dynamic motion must be tracked. The PPS probe tip and stainless steel case withstand industrial environments, while the 1.0 metre cable keeps signal integrity for close-coupled transducer systems.
Installation & Setup Guidance
Proper mounting directly affects measurement accuracy. For the Bently Nevada 330173-07-11-10-02-00, install the probe with the M8 x 1 thread and do not exceed 12 mm of thread engagement. Apply 5.1 N·m torque for the probe case; never exceed 7.3 N·m. Keep cable bends above the 25.4 mm minimum radius to prevent internal damage. During setup, maintain the reference gap of 1.27 mm (50 mils) for calibration where applicable.
Maintenance & Reliability
The Bently Nevada 330173-07-11-10-02-00 uses an AISI 304 stainless steel case and PPS tip to resist corrosion and wear. Inspect the probe cable and ClickLoc connector periodically for stress or sharp bends. Avoid operating below -34°C, as low temperatures can cause premature failure of the pressure seal. Routine checks of connector torque and cable condition reduce unplanned downtime.
Selection Guide & Purchasing Advice
Before ordering, verify the probe length options and connector style match your existing 3300 system. The Bently Nevada 330173-07-11-10-02-00 includes a miniature coaxial ClickLoc connector with standard cable and requires no agency approval option.
